After starting my vehicle with foot on the brake and putting the vehicle in gear it will move forward and occasionally roll for 4 or 5 feet before the brake engages. This is extremely dangerous as I'm pulling out of a parking space and merging with ongoing traffic !This has been going on for approximately three weeks. The vehicle literally has no brakes for four or five feet despite the fact that my foot being pressed all the way down on the brake pedal!! Last week I came very close to a major accident when I couldn't stop for an on oncoming car. Thank goodness the operator of the other vehicle stopped in time to avoid a serious accident! I immediately took the car to a local garage to have my brakes checked. They found no issues. I then took it to the Buick dealer,BICAL, and they found a serious issue. The brake vacuum pump had frozen and had actually disintegrated and no longer was functional. Parts from the pump entered the valve shaft area also. The end result was a $3,000 repair bill. The important issue here is the driver safety on the road.Although this was only occasional and at low speeds left unattended would lead to a total brake failure with major consequences and major fatalities!! God only know how many major accidents occurred with major consequences without anyone knowing the true source of the accident details. I have read online that 1996-1997 Cadillacs also have this same issue!! This is a very poor design and a major safety issue. After all there is no such thing as a minor brake issue!!! I'm avail to discuss this issue issue at your convenience. I can be reached on [XXX] [XXX] cell. Repair bill available.

I purchased my 2015 buick in May of 2015. At about December of 2017 the drivers HID head light was breached and moisture crept in creating an inner fog and eventually a puddle of water. In the falloff 2018 the same thing happened on the passengers side. I've removed both head assemblies and tried to fix the problem with very little success. Now I am looking at replacing both lamp assemblies at a cost of $2200 not counting labor.

I STARTED EXPERIENCING EXCESSIVE OIL BURN AT AROUND. SINCE THEN, I HAVE CHECKED MY OIL BIWEEKLY TO TOP OFF AND KEEP AT PROPER LEVELS ALONG WITH CONSISTENT OIL CHANGES AS THE OIL GETS DIRTY QUICKLY. DEALERSHIPS BEFORE HAVE TOLD ME THAT ITS "NORMAL" FOR THESE ENGINES. I DISCOVERED A BAD OIL LEAK. VACUUM PUMP ISSUES. MULTIPLE CAMSHAFT SEALS WORN AWAY, THAT WERE HARD AS ROCK FROM EXCESSIVE HEAT INCLUDING PISTON SEALS THAT HAD BEEN AFFECTED. THOUGHT THIS POSSIBLY HAD FIXED THE EXCESSIVE OIL BURN. A FEW WEEKS LATER I RECEIVED THE OIL LEVEL LOW NOTIFICATION ON THE CAR COMPUTER. I CHECK AND ITS VERY LOW. THE OIL BURN IS CONTINUING WITH NO CLEAR SIGNS OF AN OIL LEAK WITH DIRTY OIL. THERE IS POSSIBLY MORE PROBLEMS WITHIN THE ENGINE THAT AREN'T SEEN. I HAVE CHECKED PREVIOUS COMPLAINTS. I NOTICE THAT THIS ENGINE HAS MANY OF THE SAME PROBLEMS WITH THE TURBO PACKAGE ON GM VEHICLES. IT HAS A ROUGH IDLE AND ENGINE HESITATION. THESE CHARACTERISTICS SEEM TO INCLUDE INCONSISTENT ENGINE PERFORMANCE SOUND AND ARE FELT THROUGH THE PEDALS, THE DRIVER'S SEAT AND STEERING WHEEL, THERE IS A PUTTER AND HESITATES WHILE ACCELERATING.
